✦ Synopsis

The "post" and "prior" rorms ol Ihe scatlering T-matrix are analyzed in Lhe hghl of sudden mcchamsms of atom-molecule vib-rotauonal energy transfer. IL is pointed OUL the1 the corresponding approximatmns may be "unified" in a single "complelely orf-shell" T-mati. Applicalions of Lhe formalism LO a rolatlonal excilalion problem are in good agreemen tilh exact quanlnl calculations_ also for multiquanlum jumps I_ Post and prior sudden approximations to scattering It is well known III sxttering theory that the
